Title: Copying machine
Inventor: MIYAZA MASAO
IPC: G03G21/00
Filed: 1991-11-18
Abstract: PURPOSE:To shorten the copying time of a copying machine by controlling a pre-scanning area for each original size and therefore shortening the pre- scanning time. CONSTITUTION:A copying machine pre-scans an original 7 in order to decide the density, etc., of the original 7. The drive of a scanner 3 is controlled by a CPU 22 in a pre-scan mode. When the tip part of the original 7 is detected by the CPU 22, the moving speed of the scanner 3 is increased. Thus the original tip part is detected by the CPU 22 at a prescribed position and at the same time the movement of the scanner 3 is stopped. Then a pre-scanning operation is completed.

Title: Production of powdery ceramic stock
Inventor: OKABE KAZUMI
IPC: C04B35/628
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To produce powdery ceramic stock by grinding a powdery basic ceramic compsn. while mixing with an org. solvent and a surfactant, mixing the resultant slurry with a specified soln., removing the solvent and carrying out calcination. SOLUTION: A powdery basic ceramic compsn. is ground while mixing with an org. solvent and a surfactant, the resultant slurry is mixed with a soln. of a multiple alkoxide contg. metallic elements and the org. solvent is removed from the slurry to form a powdery basic ceramic compsn. surface-coated with the alkoxide. This coated compsn. is then calcined to produce the objective powdery ceramic stock. The alkoxide is obtd. by all-owing boric acid or boron oxide to react with a metallic acetate and a metallic alkoxide in an org. solvent represented by the formula R<1> OR<2> OH (R<1> is >=2C aliphatic hydrocarbon and R<2> is >=1C aliphatic hydrocarbon), a glycol type org. solvent or glycerol.

Title: Semiconductor device
Inventor: SHIMIZU KEIICHIRO
IPC: H01L21/331
Filed: 1986-12-18
Abstract: PURPOSE:To obtain a bipolar transistor whose breakdown strength is high and whose high-frequency characteristic is excellent by a method wherein a base for the high breakdown strength bipolar transistor is composed of a deep external base layer and a shallow active base layer and the breakdown strength between a collector and the base is decided by the external base layer. CONSTITUTION:A high breakdown strength transistor is constructed by a deep external base layer 7, a shallow active base layer 13 and a shallow emitter layer 15. Because the active base layer 13 and an epitaxial layer 3 are planar junctions, their junction breakdown strength is high; the breakdown strength between a collector and a base is decided by the junction breakdown strength between the external base layer 7 and the epitaxial layer 3. The breakdown strength between the collector and the base is decided according to the diffusion depth of the external base layer 7 and the impurity concentration of the epitaxial layer 3, and has nothing to do with the depth of the active base layer 13. Accordingly, it is possible to obtain a bipolar transistor whose breakdown strength is high and whose high-frequency characteristic is excellent.

Filed: 1990-11-07
Abstract: PURPOSE:To write a static image to one frame buffer only in a double frame buffer display system by providing a frame buffer fixing flag to be applied to a pixel. CONSTITUTION:An output of an address counter 2 is used for an address input for frame buffers 3, 4 and a flag 5 of a frame buffer fixing flag. A multiplexer 8 is a display changing means to select the content of the frame buffer 3 when the output of a gate 7 is off, and the content of the frame buffer 4 when it is on. When the frame buffer fixing flag 5 is reset, the frame buffer designated by a display frame buffer designating flipflop 6, while if the flag 5 is set, the frame buffer 3 is selected regardless of the condition of the flipflop 6. A static image therefore need only the written in the frame buffer 3.

Abstract: PURPOSE:To supply cutting papers of appropriate size regardless of document size into a picture image forming device by installing a control means which carries out roll paper cutting at a prescribed timing based on a timing where the rear edges of documents are detected by a rear edge detecting means. CONSTITUTION:When the rear edge of a document which is transferred by an exposure part passes a position detected by a rear edge detecting switch 178, the switch 178 is switched from ON to OFF to input a signal into a control device 90. The control 90 switches the first clutch 98 to OFF by the detection of the rear edge of document, and switches the second clutch 114 to ON to drive the rotation of a feed roller. Next, at the time that the pulse number of the detection signal of a rotation detector 144 reaches a prescribed pulse number, the second clutch 114 is switched to OFF. With this constitution, roll paper is transferred by a prescribed length in a roll paper cutting device 12 at a twice speed of the paper supply speed in a copying machine unit. Then, a cutter makes one turn to cut the roll paper.

Abstract: PURPOSE:To prevent the generation of reflected light and to enable precise patterning by incorporating an antireflection agent into photoresist ink to be used for patterning. CONSTITUTION:The photoresist ink 3 is applied onto a printed circuit board base 1 stuck with copper foil 2 on the surface and a photomask 4 formed with wiring patterns is placed on this photoresist ink 3 and is irradiated with parallel beams 5; thereafter, this photomask 4 is removed and the photoresist ink parts unfixed by the light 5 for irracliation are washed and peeled, by which wirings are formed. The antireflection agent composed of, for example, black dyestuff 11 for absorbing the light 5 for irradiation and fine particles 12 for matting is incorporated into such photoresist ink 3. Much of the light cast to the photoresist ink 3 is then absorbed in the dyestuff 11 without reflecting and the light failing to be absorbed is eventually diffused and reflected by the fine particles 12 incorporated therein.

Abstract: PROBLEM TO BE SOLVED: To attain smooth driving by laying a plurality of toothed driving rails parallel with a plurality of tracks of a launching slipway, and mounting a launching truck with driving gears independently driven by hydraulic motors and engaged with the driving rails. SOLUTION: At the time of launching a caisson 30, the caisson 30 is lifted by hydraulic jacks 25 of conveying trucks 20, and the trucks 20 are moved from the side part of a launching slipway 1 to the launching space of a launching truck 10 on the launching slipway 1. The jacks 25 are then lowered, and the caisson 30 is transferred from the trucks 20 onto a loading part 17 of the truck 10. The trucks 20 are moved from the truck 10 on the slipway to the side part of the slipway l. The truck 10 is then moved below the water surface on the slipway l to make the caisson float on the water surface. At this time, a gear independently driven by a hydraulic motor of each driving device provided at the truck 10 is rotated being engaged with the teeth of a driving rail 4, and the truck 10 moves on the slipway 1.  Accordingly, even in the case of defectiveness being generated to partial driving devices, other driving devices can act instead.
